waple02,

Yes, the site is still active. Honestly, I am not sure what the difference. I assume they both provide the same functionality.

Sorry I missed your question.

anybody can explain what is the difference of netmask/prefix lenght in NAT.
example:
ip nat pool mypool 198.18.184.105 198.18.184.110 netmask 255.255.255.248

ip nat pool mypool 198.18.184.105 198.18.184.110 prefix-length 29

waple02,

If you have 3 sub interfaces and one interface for the public, it might look something like this.

int f0
ip address dhcp
ip nat outside

int f1
no ip address

int f1.1
encapsulation dot1q 1
ip address 192.168.1.1 255.255.255.0
ip nat inside

int f1.2
encapsulation dot1q 2
ip address 192.168.2.0 255.255.255.0
ip nat inside

int f1.3
encapsulation dot1q 3
ip address 192.168.3.0 255.255.255.0
ip nat inside

access-list 10 permit 192.168.1.0 0.0.0.255
access-list 10 permit 192.168.2.0 0.0.0.255
access-list 10 permit 192.168.3.0 0.0.0.255

ip nat inside source list 1 interface f0 overload

This might not be exactly correct. Doing it all from memory. I will try to check my work later.

Hi Josh,
Do you have a tutorial on how to configure a VPN with NAT hide before VPN. I need to create a tunnel betwen two companies but one of them works with public adresses and do not accept rfc 1819 addresses.
Thanks in advance
